本次提一下2012年 ReEconSta的一篇文章，先看一下摘要部分：
Abstract—We investigate how the link between individual schooling and political participation is affected by country characteristics. Using individual survey data, we find that political participation is more responsive to schooling in land-abundant countries and less responsive in human capital–abundant countries, even while controlling for country political institutions and cultural attitudes. We find related evidence that political participation is less responsive to schooling in countries with a higher skill premium, as well as within countries for individuals in skilled occupations. The evidence motivates a theoretical explanation in which patterns of political participation are influenced by the opportunity cost of engaging in political rather than production activities.


我简单总结一下：
国家特征如何影响入学教育与政治参与的关系。基本发现有如下特征
1， 地域辽阔的国家，政治参与易受入学教育的影响；
2，人力资本丰富的国家，该影响较小；
以上两点，在考虑了国家政治制度和文化态度，依然成立。
3，在高技能premium较高的国家，该效应较小；
4，在高技能职业较高的国家，该效应较小。
5，初步构思理论框架如下：政治参与的模式，要受到参与政治活动的机会成本，而不是生产活动的机会成本的影响。

针对以上结论，大家伙可针对一点或两点展开说说。
（本文似乎带点政治性的讨论，因此建议大家不要脱离本文的话题而泛泛而言。）

A，回归方程：
政治参与程度=beta1*个体特征向量+beta2*个体教育程度+beta3*个体特征向量×国家特征+beta4*国家固定效应+cluster effect+error term
B，数据来源：World Values Survey (WVS), a rich study of sociocultural attitudes around the world. Four waves of the
WVS are available (conducted in 1981–1984, 1989–1993, 1994–1999, and 1999–2004)
C，政治参与程度变量构造所使用的WVS数据：
1. Interest in politics (question E023): “How interested would you say you are in politics?” 0 = Not at all interested, 1 = Not very interested, 2 = Somewhat interested, 3 = Very interested.
2. Importance of politics (question A004): “For each of the following aspects, indicate how important it is in your life. Politics.” 0 = Not at all important, 1 = Not very important, 2 = Rather important, 3 = Very important.

3. Discuss politics (question A062): “When you get together with your friends, would you say you discuss political matters  requently, occasionally, or never?” 0 = Never, 1 = Occasionally, 2 = Frequently.
4. Petition (question E025): “Now I’d like you to look at this card. I’m going to read out some different forms of political action that people can take, and I’d like you to tell me, for each one, whether you have actually done any of these things, whether you might do it or would never, under any circumstances, do it. Signing a petition.” 0 = Would never do, 1 = Might do, 2 = Have
done.
5. Demonstrate (question E027): Same question as for Petition, now referring to “Attending lawful demonstrations.” 0 =Would never do, 1 = Might do, 2 = Have done.
